The government made public for the first time this week the details of the ranking system it will use to give skilled immigrants express entry into Canada within six months, starting Jan.1.

A total of 1,200 points will be allotted under the new system, but there's no minimum points level required to qualify. Only the "highest-ranking" candidates will be "invited to apply" for permanent residency.

These are the candidates that will be "picked first," Immigration Minister Chris Alexander said Monday in a written statement.

Up to 500 points will be allotted for age, education level, language proficiency and work experience in Canada, while a maximum of 100 points will be allotted for a combination of education level, foreign work experience and a certificate in the trades.

According to Statistics Canada's 2011 National Household SURVEY, immigrants to Canada are increasingly younger, more educated, and speak more languages.

The median age of newcomers in 2011 was 31.7 years, compared with 47.4 for the total immigrant population. A greater number of newcomers between 2006 to 2011 had an undergraduate degree in comparison to those who immigrated to Canada before 2006. Among recent immigrants, 66.8 per cent were able to speak English or French and one or more non-official languages, in comparison with 61.2 per cent of all immigrants.

Here are three examples of how prospective candidates could be ranked under the new system:
